fibers laid together or on separated fibers which are united at the time of twisting. The apparatus employed for such an operation is usually a French or Yorkshire winder or a continuous ring or wing type silkthrower which are always provided with a transmission arrangement such as bobbin carrying spindles for the twisted or untwisted material and are rotated synchronously with the spindles.

Such a manner of operating presents a number of disadvantages, among which are uneven twisting, irregularity in the number of turns over the entire length of a set of twisted fibers, by reason of the raising and lowering of the carriage for conical or cylindrical bobbin filling and tension on the thread to be twisted during descent of the carriage which has the reverse effect on the carriage during ascent thereof. Furtherso more the twisted material is not identical throughout its entire length.

It is one of the objects of our invention to provide a method and apparatus for effecting twisting which will eliminate or at least attenuate the defects above noted and in which the output is bettered, the operation more steady and the product more perfect.

A more specific object of the invention is to allow the spindles carrying the bobbins of the material to be immovable by imparting rotation to the thread only.

These objects are realized by disposing the one or more bobbins of the thread to be twisted in the center of a rotating protecting system traversed by the thread which enters therein in conformity to the axis thereof and which leaves therefrom in conformity to the said axis in twisted state and is then wound on a winding device having regular feed.

In this way the output is increased in very large proportions due to the fact that at each revolution of the rotating system two turns are produced in the twisted material and that the thread being protected from the dissociating action of the air may be rotated at much higher speeds.

The speed of the rotating system producing the twisting operation is therefore no longer dependent upon the driving of the material carrying bobbin from which it is completely liberated and speeds of from thirty to forty thousand revolutions can be realized with ease.

The weight of material wound on the bobbin can be increased without difficulty and stops or interruptions for gathering material will hence be less frequent. There results therefrom an economy in manual labor as the number of tyings necessary from one twisting operation to another are diminished.

Furthermore twisting periodicity disappears and the twisted material is uniform.

Other objects of the invention will be obvious to those skilled in the art to which the invention appertains in the following description when taken in connection with the accompanying drawing forming part of this specification and in which Fig. 1 is a longitudinal sectional view of the apparatus with parts in elevation; and

Fig. 2 is a sectional detail of the guiding arrangement on an enlarged scale.

The apparatus which is about to be described from a mechanical standpoint of view for carrying our method into practice may obviously include devices of current type known in the art which the operation thereof necessitates as the device must be able to turn at speeds which are only limited to the 15 scribed. 1

The shaft 2 is fitted in a protecting cylinder of circular or polygonal cross section which forms the principal part of our invention. I

-- Said cylinder is constituted by two cylin der heads 3 and 4 and abody 5.

The body 5 is of as light a. metal as possible but with sufficient resistance toresist the action of centrifugal'force. Said cylinder -.is providedwithtwo openings or slots 6, which through rotation, establish the possibility of following the thread as will be hereafter de- The head 3 is fitted over an extension 7 of shaft 2 (Fig. 2 which is pierced. with an axialchannel 8 and provided with a small transmission pulley 9. The thread T to be twisted leaves through said channel.

Head 3 is provided with a groove 10 serving as a thread guide and out along the diameter thereof. The said thread T enters the extends through a groove 12 provided in the bod 5 of the cylinder. The said groove ends at t e head 4 where the thread proceeds over a pulle 11', descends in a diametrical groove 10 an passing over a counter pulley 9' ex tends through a channel 8 furnished in a stud shaft 7 The member 7 is disposed exactly in axial alignment withthe member '7 and serves as a spindle support for cyliner 5.

" The spindles 7 and'7 supporting cylinder 5 are. mounted in bearings 1313"and of which 13 carries the driving shaft.

As hereinbefore statedthe assembled threads extend through the channel 8, pass groove 12, over pulley 11, through groove 10 over pulley'9 and out through the Opening 8, openings 8' and 8 being disposed in bobbinwoul '-lie ,in-.line with the sp1nd1"es":

' exact axial alignment. A pulley 14 is preferably provided at the end' of tube 7' for guiding the thread in twisted stateto the winder. v y y The assembled untwisted threads, which are to be subjected to twistin by rotation of the arrangement are carrie by a'bobbin 15. Said bobbin is preferably that which;

was used in assembling the threads, and is adapted tobe passed through the slots 6 provided in cylinder 5. V K

Bobbin 15 is supported by a stirrup 16 suspended on ball bearings 17-17.carried by the inner ends of shafts 7 7., On; said stir rup is'monuted a shaft 18 I which carries 'a.

ball-bearing sleeve 19 adapted to receive the bobbin 15. The arrangement is such that a' middle plane assed horizontally through the sitely disposed to pulley 20 is carried by a member 22 slidably mounted on .a bracket 22 fixed to stirrup 16. The said member 22 is provided with a pair of pins 23 which engage in a slot 24 of bracket 22', the said v slot terminating at its lower extremity in a notch 25 forming a stop for retaining the pulleys separated in open position. The disposition of the whole is such that the pulleys meet each other at a point exactly in line with the opening 8.

Upon leaving the apparatus'after passing over pulley 14, the thread Tin twisted form is led to a winding device which has not been disclosed since it may be of current type known in the art having a constant pitch for I forming cops of the twisted product. cylinder by passing over a pulley 11. It then The above described device operates in the following manner:

Assuming that the assembling bobbin 15 is ready, the Iirst "operation consists in engaging the thread T. F or'the following operations, it is sufficient totie the thread to the end of the thread of the preceding bobbin which has been exhausted.

After raising the roller 21, which is mainguiding of the thread and the device set'in motion. "The assembled thread T moves in the direction of opening 8 and the twisted thread leaves in the direction of opening 8 whereas the portion thereof extending through groove 12 is rotated about the axis of shafts 8-8 which produces a twist in the thread leaving through 8' as will be readily understood by those skilled in the art. 1

While the bobbin 15, during this time, re-

mains in an absolutely definite position,it

which couple of friction is opposed to gravi- I tation of the stirrup 16.

The said bobbin, however, remains rigorously stable with its shaft immovable al-' though not fixed. v

a The bobbin is thus very easily emptied and jolting or movements of any sort andwitli regularity in view of the symmetrical disposition of shafts 8-8.

The disposition of the entire twisting loop of thread T in slots protects the thread from the dissociating action of the air when said loop is rotated and the operating speed of the loop may be increased six fold over what it usually is without danger of rupture of the thread through dissociation from windage.

The progress of the unwinding operation may be observed through openings 6 and at the proper moment the apparatus is stopped by disengaging the motor and braking the cylinder. The empty bobbin is then removed and a new bobbin placed on spindle 1819, the end of the thread from the old bobbin being tied to the end of that on the new bobbin and the cycle of operations is repeated as above described.
